An invoice has a subtotal of $42.60 for the items, a new customer discount of $5.00 to be applied before taxes, and a sales tax of 7.5%. What is the correct invoice total?

A.
$40.79

B.
$40.42

C.
$51.17

D.
$45.10

The correct invoice total can be calculated as follows:

First, subtract the customer discount of $5.00 from the subtotal of $42.60:
$42.60 - $5.00 = $37.60

Next, calculate the sales tax of 7.5% on the revised subtotal:
$37.60 * 0.075 = $2.82

Finally, add the sales tax to the revised subtotal to get the correct invoice total:
$37.60 + $2.82 = $40.42

Therefore, the correct invoice total is $40.42.

The answer is B. $40.42.

To calculate the correct invoice total, you need to follow these steps:

1. Subtract the discount from the subtotal: $42.60 - $5.00 = $37.60.
2. Find the amount of sales tax by calculating 7.5% of the discounted subtotal: $37.60 * 0.075 = $2.82.
3. Add the sales tax to the discounted subtotal to get the invoice total: $37.60 + $2.82 = $40.42.

Therefore, the correct invoice total is $40.42. The answer is option B.

To find the correct invoice total, follow these steps:

$37.60 * 0.075 = $2.82

Step 3: Add the sales tax to the discounted subtotal:
$37.60 + $2.82 = $40.42

Therefore, the correct invoice total is $40.42.
